About Perfection! 4: Nightfall
The game is deceptively simple. Make all of the tiles on the game board point to midnight (or North if you prefer.)
Sounds simple enough, but this is a puzzle game. So when you rotate your selected tile, the tiles above, below, left and right of it which match any of the colours on the button also move. each button may have up to four colours, so you have to find the right combination of button and tile to move in order to get them all pointing to midnight together.
